OSX does have fdatasync defined as part of the libsystem_kernel.dylib library.
The problem is that there is no header on OSX that actually provides the
function.
There is another issue where I redefined PRIuMAX to "llu" and PRIdMAX to "lld"
on OSX. This was necessary because the build was picking up the lib/stdint.h
provided with coreutils. In there we ended up defining uintmax_t as a uint64_t.
<snip>
#elif defined GL_UINT64_T
# define uintmax_t uint64_t
#else
</snip>
However by default on OSX, PRIdMAX is defined as "jd" and PRIuMAX is defined as
"ju."
I have added a hack to get coreutils to compile cleanly on OSX. Hope this
helps.
